The OP was updated in 13-6-2021I loved shooting in Higher resolution Modes with ML, I hated the cropped Preview in these Modes, that was the major pain for me, The Preview . .
I spent the last three weeks trying to understand How Preview registers works, hopefully I would get something, and I got it:
Introducing the New Expanded Real-Time preview in x5 Mode
650D / 700D:
This buildEOS M:
This build from Danne (Thanks!)
Features:
1- Real-Time Responsive Preview as Normal 1080p Mode preview.
2- Accurate Aspect Ratio out of the box, No ML Global Draw is needed.
3- No slowness and No overhead, which means no corrupted frames and no drops in write speed.
4- Accurate Framing Preview if you consider there will be data in the right instead of Black Bar.
5- Works on HDMI monitors too.
Known Limitations:
-Black Bar in the right instead of the right part of actual RAW data.
Notes:-The Preview is in the Top Part of the screen, not centered on
screen.
-You may compare ML Framing vs The New Preview to trust it.
-
Turn OFF Global Draw for better Preview. (
Edit: No longer needed on 650D / 700D builds).
-Feel the responsive.
-Instead Normal of x5 Mode Preview? Wow!
-Still working on Black Bar limit.
Q&A1-
What about Higher Resolutions like 3K, 4K?-Didn't try yet, I guess it should work, at least we could get the new preview for Normal x5 Mode (2520x1080) and apply it on 3K resolution, but with more Black Area in the right and cropped height.
2-
1x3 Binning Mode?-
Something still puzzling me for increasing the Height Preview in None-Zoom Modes, no luck yet, However 1x3 Mode is more important to me compared to x5 Mode, I am working on it hardly.
Edit: Yes it works, you will find 1x3 presets with real-time correct framing preview in custom crop_rec builds, currently it's only for 650D / 700D / EOS M.
3-
Other Cameras?-This development and research started on 700D, fortunately EOS M has benefited too, because it has Identical registers and values as in 700D, no further modifications happened, same preset Works on both cams, also 650D might be identical and 100D might be very similar (I can take a look for 100D, 650D if registers were the same, let me know if there a volunteer), However 5D3 doesn't share the same set of registers, 6D also might be different, I can't work on other cameras, Sorry, I don't have them.
4-You got correct Aspect Ratio for this Preview without ML Anamorphic setting,
Could we use same method for correcting Aspect Ratio instead of ML Anamorphic setting to be used for Anamorphic Lenses?
- Yes, we can fix Aspect Ratio without ML Global Draw, with very responsive LiveView.
5-
I am photographer?-I am not here.
6-
Is it possible to make 1080p 1:1 preset in Crop Mode with Real-Time Correct-Framing preview?-
Yes, Let me know if you need it. (
Edit: We did it, 1920x1280p 1:1 preset).
-Let's keep this thread for testing and sharing thoughts about this topic, this development started from
LiveView Investigation.
Have fun.
